Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for producing underwear using a cylindrical long fabric, such as a knitted or woven fabric, for cutting the front side of the fabric and the back side of the fabric into the same size and shape. .

When manufacturing underwear using knitted or woven fabrics, long cylindrical fabrics are cut into small and large pieces into the desired shape. Conventionally, long cylindrical fabrics are usually stretched using a spreading machine. The fabric is then cut to size, and then the cut fabrics are stacked one by one for fabric inspection.
Cut the stacked fabric into the desired shape and make it around the neck.
The shape was around the sleeves, which required a lot of man-hours and effort.

Also, when cutting laminated fabric, if the cutting line is a complicated curve or a sharp mountain shape, if you try to cut it by hand, it will take more than the necessary fabric area. In order to facilitate the cutting work, extra fabric area is required for play, resulting in a decrease in fabric yield.

Therefore, there is a need to automate a series of tasks such as sending out long cylindrical knitted fabrics in fixed quantities and cutting them into large and small pieces. It becomes necessary to consider the special characteristics of

In other words, knitted fabrics are highly flexible and stretchable, so it is important to shape and maintain their shape before sending them out.Also, in the case of cylindrical fabrics, the front and back sides of the fabric are in contact with each other, so Even if it is sent out using a roll or the like, there is a risk of misalignment.

Based on the above viewpoint, as a result of intensive research, the present inventors sandwiched a fabric guide core material between a pair of fabric feed rotating bodies that mutually drive in the fabric feed direction, and attached a cylindrical long fabric to the fabric guide core material. The fabric guide core material is configured to be fed in the longitudinal direction of the tube in a state in which the fabric guide core material is covered with a notch window formed in the fabric guide core material, and an axis of the fabric guide core material is installed in the notch window so that the axis thereof is in the width direction of the fabric. a support shaft, an eccentric roller eccentrically fixed to the support shaft in a direction protruding from both surfaces of the fabric guide core material, and a ring body rotatably fitted onto each of these eccentric rollers and rotated in contact with the fabric. A cylindrical long fabric feeding device characterized in that the ring body engages with the outer circumferential surface of the rotating body on the fabric insertion side through the fabric, and prevents the fabric guide core from moving along with the fabric. The development was successful.

Therefore, according to the present invention, the fabric guide core material is sandwiched between the fabric feeding rotating bodies, and the core material prevents contact between the front side of the fabric and the back side of the fabric, thereby eliminating misalignment between the front and back sides during the feeding process. .

In addition, since the fabric guide core material is provided with a contact rotating body that is exposed from both sides and inflates the fabric, it not only forcibly prevents contact between the front and back sides of the fabric and prevents the front and back slippage, but also The contact rotary body also has the function of positioning the core material, and the structure can be expected to be simplified, which is an advantage.

A conveyor 44 is provided in front of the stack conveyor 41 via a chute 45.

The embodiment of the present invention is as described above, and its operation will be explained below.

First, as shown in FIG. 4 or FIG.
The fabric is passed through the core material 10 and applied, and the tip of the fabric is positioned at the tip of the formwork 7. Next, the dough presser 2
4' is swung through the extension of the cylinder device 28, and the presser body 24' presses and clamps the fabric Q against the formwork 7 side. Next, only the small cutting cutter 31 shown in FIG. 8 is lowered to cut the vicinity of the edge of the fabric into an appropriate shape.

That is, as shown in FIG.
Since the cutting edge of the small cutter 31 has the same shape, when the cutting edge 31a of the small cutting blade 31 descends onto the cutter receiving member 30, the cutting edge 31a touches the edge of the formwork 7 as shown in FIG. It descends to the position shown by the two-dot chain line 31a outside the edge-cutting portion 6a, and the fabric is accurately cut.

That is, when cutting the fabric by lowering the cutting edge 31a onto the cutting receiving member 30 with the edge of the fabric positioned on the cutting receiving member 30 outside the edge molding portion 7a of the form 7, the cutting edge 31a descends along the outer edge of the edge molding portion 7a, so that the cutting is performed accurately without any deviation in shape or size.

Next, when the cylinder device (see FIG. 1) serving as the formwork driving means 8 is extended, the formwork 7 is moved to the right in FIG. It is rotated in the fabric feeding direction in synchronization with the movement.

That is, as particularly illustrated in FIGS. 5 and 6, the ring bodies 21a, 22a, and 23a that fit around the eccentric rollers 21, 22, and 23 provided on the core material 10 as positioning locks are bulged. The state is
In addition, as shown in FIG. 4, the guide leg portion 1 of the core material 10
A feeding position is taken in which the left and right side edges 13 of 2 prevent the fabric Q from shifting in the width direction, and the fabric Q is pressed and clamped by the fabric presser 24' and the formwork 7, so that the driving means 8 is extended. Then, the fabric Q has a core material of 10
and is fed out a constant amount without any sideways vibration. At this time, since the rack 4 of the conveying member 2 and the pinion 20 are engaged with each other as the formwork 7 moves, the pinion 20 rotates, and the pair of dough feed rotors 14 are interlocked by the gears 17 and 18. Moreover, when the fabric Q runs, the ring body 21
a, 22a, and 23a are rotated by frictional force and are locked on the side opposite to the feeding direction of the fabric feeding rotary body 14 to ensure the positioning of the core material 10.

In addition, the dough Q placed on the formwork 7 moves together with the formwork 7 while being pressed by the dough presser 24', and in the embodiment, the dough Q is quantified until it reaches the vicinity of the starting end of the stacking conveyor 41. It will be sent to you. At this time, the cut waste after the small cutting is pushed by the formwork 7 while the formwork 7 is moving, and is sucked and removed by the collection box 33 on the way. Further, the relay conveyor 34 also moves to the right in FIG. 8 through the extension of a cylinder device (not shown), and is located above the stacking conveyor 41.

Next, the relay conveyance body 34 shown in FIG. 8 moves in the opposite direction to the left in the same figure, waits below the formwork 7, and presses the fabric Q in the longitudinal direction with the fabric pressers 38 and 39. On the other hand, the dough presser 2 provided in the formwork 7
4' is released via a retracting movement of the cylinder device 28. After releasing the dough presser 24', the driving means 8 is retracted to move the formwork 7 shown in FIG. 8 back.

That is, when the fluid cylinder device of the drive means 8 shown in FIG. It returns to the X position shown. At this time, even if the pinion 20 is engaged with the rack 4 of the conveying member 2, this pinion 20 has a one-way clutch built therein, and depending on the backward movement of the formwork 7, the dough delivery rotor 14 can be moved. Since it is not rotated, there is no shrinkage of the fabric Q, and the fabric Q
Since it is pressed by the pressers 38 and 39, shrinkage is completely prevented.

Therefore, even if the formwork 7 moves back as shown in FIG. 8, the fabric will not sag because the relay conveyor 34 supports the leading edge of the fabric.

Thereafter, the fabric holding body 24' provided in the formwork 7 advances against the formwork 7 through the extension of the cylinder device 28, presses the fabric Q, and at the same time presses the fabric Q and presses the large cutting cutter of the cutting device shown in FIG. 32 and small cutter 3
1 will descend together to obtain a sizing fabric of the desired shape. During the cutting operation of such a cutting device, the formwork 7
The guide body 29 restricts the lateral vibration and the like.

After that, the cutters 31 and 32 of the cutting device and the fabric presser 38 of the relay conveyance device rise, and then the cylinder device as the drive means 8 extends, and the relay conveyance body 34 is moved to the right through a cylinder device (not shown). move back and forth.

At this time, since the formwork 7 supports the dough Q and also holds the dough Q with the dough presser 24', the dough Q is fixed from the X position to the Y position in FIG. 7 in the same way as described above. We will send out only a small amount. In other words, as described above, the material feeding rotary body 14 is synchronously driven in the feeding direction through the engagement of the rack 4 and the pinion 20 as the formwork 7 moves forward.
Also, at this time, the cut waste is sucked and removed by the collection box 33, and the relay conveyor 34 is stacked on the conveyor 4.
It reaches above 1.

Next, the pressure of the fabric presser 39 in FIG. 8 is released, and the conveyor 34 moves to the left in the figure while the fabric presser 43 descends and presses the sizing fabric separated by the cutting. Waiting below the form frame 7, the fixed-sized fabrics are stacked and transferred onto the conveyor 41.

Next, the dough presser 43 is raised, and the dough is pressed by the dough pressers 38 and 39 shown in FIG.
moves to the left in the figure, and the same operations as described above are repeated.

In addition, when the required number of cut fabrics are stacked on the stacking conveyor 41, the conveyor 41 is circulated and transferred to the conveyor 44.

As explained in detail above, the present invention, for example, when feeding a cylindrical long fabric into a cutting device in fixed quantities, the cylindrical long fabric is placed on a fabric guide core material, and the core material retains its shape inside the fabric.・Since the fabric is fed while being shaped and the fabric is fed without contact between the front and back sides, it has the advantage of ensuring that there is no deviation in the feeding direction.

Furthermore, the fabric guide core material is sandwiched between a pair of fabric feed rotating bodies that drive it in the feeding direction, and not only can the core material be positioned using an eccentric roller or a ring body, but it can also be positioned externally on the eccentric roller. It has the advantage of being able to inflate the cylindrical fabric with the ring body and feeding it smoothly and accurately.Moreover, since the eccentric rollers 21, 22, and 23 are fixed sharing a single spindle 25, each Eccentric rollers 21, 22, 2
There is no need for a support shaft for each of the three, and the structure is therefore simple and advantageous.
